Syntax

Objective-C

C++/CLI

Java

Python

public int Brightness { get; set; }

@property (nonatomic, assign) NSInteger brightness;

public int getBrightness(); 
public void setBrightness( 
   int intValue 
);

public: 
property int Brightness { 
   int get(); 
   void set (    int ); 
}

Brightness # get and set (ContrastBrightnessIntensityCommand)

Property Value

Value that refers to the color intensity scale factor. The brightness ranges from -1000 to 1000. This value is divided internally by 1000. A positive value increases (or lightens) the brightness of the image. A negative value decreases (or darkens) the brightness of the image.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ContrastBrightnessIntensityCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   ContrastBrightnessIntensityCommand command = new ContrastBrightnessIntensityCommand(); 
   command.Contrast = -146; 
   command.Brightness = 358; 
   command.Intensity = 240; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS

   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
